Abstract

Abstract: To save inevitable modeling insufficiencies owing to the simplified modeling strategie, simulation system of gear hobbing process based on solid modeling was developed. To realize the precise modeling of hob tooth moving trace, the vector model of the gear hobbing motion based time-driven was put forward, and then the position vector and velocity vector for every trace point were obtained. The velocity vector was specified as first-order vector, position vector as node coordinate and both of them were used to get hob tooth moving trace curve by the spline interpolation. Interpolation accuracies of hob tooth trace curve were obtained under different number of interpolation points and the most suitable number was selected. The trace curve was applied to the gear hobbing simulation system developed. The validity and accuracy of the proposed method were confirmed by comparison between the produced gear gap profile and theoretical one.
